What have you tried so far and which problems occurred? How can we assist you to solve your problem?

You could set a flag when you hit start, for example
isRunning = 1;
setappdata(handles.myPushbutton,'isRunning',isRunning);
and also change the text of the pushbutton to stop
set(handles.myPushbutton,'String','Stop');
Finally you could implement a timer object to easily implement the start/stop functionality of the plot.
So the final callback would be something like:
isRunning = getappdata(hObject,'isRunning')
if isRunning
stop(myTimerObject);
isRunning = 0;
setappdata(hObject,'isRunning',isRunning);
else
%setup and start timer
isRunning = 1;
setappdata(hObject,'isRunning',isRunning);
end
In fact you don't really need the isRunning variable as you can find that out directly from the timer object. I'm just to lazy to redo this post.

What I described does that. You would have to define what goes in each section of the code to start/stop/create the timer.
